These two exceptions do not occur very often. When I complete about 100 task instances , 10 or less cases may come to these two exceptions. The version is jbpm 3.2.2 and I use oracle 10g .    I have checked the hibernate_sequence and the hibernate configuration.    I just complete an existing task instance in a single transation.    Any one can help me ?   2010.01.06-09:26:26 [WebContainer : 5] ERROR org.hibernate.util.JDBCExceptionReporter -
